Chemistry: Chapter 10: Stoichiometry
What is the measured amount of product obtained from a chemical reaction?
Actual yield
To determine the limiting reactant in a chemical reaction, one must know the
Available amount of each reactant
What is mole ratio?
Conversion factor between two substances. You need the mole ratio to solve Stoichiometry problems
What is the limiting reactant?
Determines the amount of product that can be formed by a reaction. Totally used up.
What are reminders for Stoichiometry?
Equations must be balanced 1 mol = Molar mass 6.02x10^23 particles 22.4 L
In most chemical reactions, the amount of product obtained is
Less than the theoretical yield
Which reactant controls the amount of product formed in a chemical reaction?
Limiting reactant
What is reaction Stoichiometry?
Mass relaitionships between reactants and products in a chemical reaction
A mole ratio allows one to determine the..?
Mole ratio of any 2 substances in a reaction
What is the rain of the actual yield to the theoretical yield, multiplied by 100?
Percentage yield
What is the excess reactant?
Reactant that is not completely used up.
When the limiting reactant is a chemical reaction is completely used up, the
Reaction stops
Which branch of chemistry deals with the mass relationships of amount reactants and products?
Stoichiometry
What is percent yield?
The percent of the theoretical yield that was made by our experiment. Actual amt./ theoretical yield x100
What is the maximum possible amount of product abstained in a chemical reaction?
Theoretical yield
What does liters measure?
Volume
